  • What are vegetable oils derived from?
  • There are numerous vegetable oils derived from various sources. Soybean, sesame, sunflower, corn, canola, and cotton seeds are the most commonly used raw materials for the production of edible oil . Their yields, compositions, and physical and chemical properties determine their usefulness in various applications aside from edible uses.
  • What is vegetable oil refining?
  • Refining of edible oil is a process where free fatty acids are volatilized, condensed, and recovered simultaneously with vacuum decoloring operation. However, processes in vegetable oil refining, such as filter backwash, acidification of soap-stock, and washing of equipment, produce big amounts of wastewaters .
  • What is the industrial processing of vegetable oils?
  • The industrial processing of vegetable oils has become increasingly standardized based on national or international standards, and high-capacity production of extraction and refining has been realized .
  • Why do we use microwave pretreatment enzymatic method in Camellia oleifera seeds?
  • In addition, Zhang, Zhang and Chen used a microwave pretreatment-assisted enzymatic method to obtain a high oil yield (95% of the total oil in the seed) from Camellia oleifera seeds because microwaves could disrupt the structure of the cotyledon cell walls and lipid bodies inside these cells and then facilitate the release of the oils .
  • How much oil can be extracted from vegetable oil crops?
  • Table 1. Extraction of vegetable edible oils from oil crops. Maximum oil extraction yield = 55.47%. T = 60¨C65 °C, Solvent = n-hexane.
  • Are vegetable oil refinery wastewaters biodegradable?
  • The BOD 5 /COD ratios of the factory wastewaters are 0.15 and 0.2 for corn oil and sunflower oil refining wastewaters . Aslan et al. investigated the biodegradability of vegetable oil refinery wastewaters and concluded that they have a low BOD 5 /COD ratio and that these wastewaters cannot be treated only by biological treatment.
